SAUNIER DUVAL split aerothermal systems

The new Saunier Duval Genia Air split units have been added. Within the air-source heat pump, water/air conditioning systems, under the Saunier Duval logo, users can choose between the compact Genia Air series and the new Genia Air split. Within the latter, users can select the different outdoor unit models and their corresponding indoor unit, of the hydraulic module type or with an integrated Genia Set split accumulator.

As for the rest of the air-source heat pumps, users can choose whether the system will be used only for heating or also for cooling. Furthermore, users must specify the working temperature conditions of the installation and its operating mode during the year.

Saunier Duval Genia Air split units have also been incorporated into the DHW Systems panel. Additionally, FEW monovalent and FEWS bivalent DHW accumulators have been added, which will appear when an indoor hydraulic module unit is chosen. These accumulators can also be selected in conjunction with Saunier Duval compact air-source pumps.

Open BIM workflow. Import air conditioning equipment from “Open BIM SAUNIER DUVAL”

SAUNIER DUVAL aerothermal equipment and fan coils defined in "Open BIM SAUNIER DUVAL" can be imported directly into CYPETHERM EPlus via the Open BIM connection using the IFC standard. If this equipment is associated with a CYPETHERM Hydronics project, the connections between them will also be imported.

VAILLANT geothermal heat pumps

As of its 2020.c version, CYPETHERM EPlus is capable of simulating air conditioning systems with air-water heat pumps based on the behaviour curves of this equipment, and incorporates the VAILLANT geothermal heat pump catalogue.

Geothermal water-water heat pumps appear as a new category in "Water-air conditioning systems". In the panel that appears when clicking on the new "Geothermal" button, users can choose amongst different models of VAILLANT geothermal heat pumps for heating (geoTHERM series) or reversible (flexoTHERM and flexoCOMPACT series). Additionally, users must specify the operating conditions of their installation.

The geothermal heat pump must be connected to a water condensation system at a defined temperature, also available as of version 2020.c of the program. This type of system allows users to simulate the conditions of the fluid at the inlet of the outdoor side of the heat pump, for example from a collector circuit.

Geothermal heat pump systems can be connected to terminal units such as radiators or radiant floors (heating only) and to fan coil units (heating and cooling).

Furthermore, geothermal heat pumps have been included within the DHW production equipment. In this panel, users can choose between the different VAILLANT flexoCOMPACT series models.

Using the "Assistant" button of the toolbar, the program will guide users when creating a geothermal air conditioning and DHW system, allowing them to select the appropriate terminal units, heat pump and condensation system consecutively.

DHW accumulators

Within DHW Systems, users can now define DHW accumulators, to be able to account for the effect of their heat losses on energy consumption for this building service.

The DHW accumulators are defined within the corresponding DHW System, using their global loss coefficient (UA). An assistant is provided to calculate the UA value of the accumulator based on its dimensions and its insulation properties. The heat losses produced in the DHW accumulators represent an increase in the demand for energy, which will be provided by the production equipment that is associated with the same DHW system.

An accumulator associated with a specific DHW production equipment set can also be defined. In this case, heat losses due to the accumulation will be compensated only by that production equipment. This option allows users to define equipment such as electric heat accumulators or heat pumps for DHW.

Water-condensation system at a specific temperature

Within the "Water-condensation systems", a "Water condensation system at a specific temperature" has been added. This type of system can simulate any water or glycol circuit connected to the external exchangers of the air conditioning equipment. For example, it can be used to simulate a field of geothermal collectors or a groundwater stream. To do so, users must only define the temperature of the fluid at the circuit outlet and the properties of the circulation pump.

This new condensation system is compatible with coolers and outdoor VRF units with water-cooled condensers, as well as with water-air heat pumps.

DHW systems with several production units

The ability to define several production equipment sets associated with a DHW system has been added. Users must indicate what percentage of the DHW demand that is associated with the system covers each defined equipment set.

As in previous versions, DHW systems are defined in the "DHW Systems" diagram section. If the "Total building demand" option has been selected in "General parameters", users can define the DHW system of the building directly by clicking on "DHW Systems" in the diagram.

If the “Demand by thermal zone” option has been selected, the “New DHW system” button of the toolbar must be used to define the DHW systems. This new function allows users to define the DHW systems that see to the different areas of the building, in a single step.

Import equipment from Open BIM VAILLANT

As of the 202.b version, VAILLANT aerothermal equipment and fan coils that have been defined in “Open BIM VAILLANT” can be imported directly in “CYPETHERM EPlus” with the Open BIM connection using the IFC standard. Additionally, if this equipment is associated with a “CYPEHVAC” project (design of water distribution installations for air conditioning), which is connected to the same Open BIM project, “CYPETHERM EPlus” also imports the connections between them.

SAUNIER DUVAL DHW heat pumps

The catalogue of heat pumps for domestic hot water production (DHW) "Magna Aqua" by SAUNIER DUVAL has been added. Within DHW Systems, when “Heat pump for DHW” is selected, the SAUNIER DUVAL logo appears. By clicking on it, users can choose amongst the different models the manufacturer has to offer.

The specifications of these devices depend on the type of weather selected in "SPF climatic conditions", within the "Location data" panel.

SAUNIER DUVAL fan coils

The SAUNIER DUVAL "Genia Fan" fan coils catalogue has been implemented. Within the Fan coil-type water air conditioning terminal units, the SAUNIER DUVAL logo appears. In the panel that opens when the logo is clicked on, users can choose amongst the different fan coil types and models this manufacturer has to offer. The equipment is fully defined in the program.

Fan coils must be connected to a water air conditioning system, either of the water distribution type or of the aerothermal type. They are compatible with the water production equipment of all the other manufacturers.

VAILLANT fan coils

The VAILLANT "aroVAIR" fan coils catalogue has been implemented. Within the Fan coil-type water air conditioning terminal units, the VAILLANT logo appears. In the panel that opens when the logo is clicked on, users can choose amongst the different fan coil types and models this manufacturer has to offer. The equipment is fully defined in the program.

FUJITSU “Airstage” VRF equipment catalogue update

The new references of the FUJITSU VRF "Airstage" outdoor and indoor units from the 2019 catalogue have been included.

New options in the constant performance equipment: power and programming

An option has been added to define the heating and/or cooling power of "Constant Performance Equipment" type terminal units. If the power is not specified, the equipment will overcome the thermal load of the area where it is located, according to the activation sequence of the terminal units defined in the area.

Furthermore, the equipment operation schedule can be defined. Users can choose the equipment that is always available to overcome the load, as until now, or establish an operating schedule.
